Well, it's only 4X4, and she can get started on 6X6...
Anyway, does anyone know where I can get more 4X4's or 6X6's because the book she has is almost finished.
Or maybe a generator I can set to 4X4?
Thanks in advance!

Your info says "There are 36 ways to place 4 digits...which yields one solution."
If there are minimal puzzles with 5 clues, and 6 clues, then the number of puzzles must include the set of your puzzles, plus others, yielding a total of more than 36.
Thus, the number of non-equivalent minimal 4x4 Sudokus remains either unresolved, or answered with ambiguous and/or contradictory statements.
